摘要:

以Ca(NO3)2·4H2O和(NH4)2HPO4水溶液为前驱体, 采用水热均相沉淀法制备了结晶度较高的羟基磷灰石纤维, 研究了表面活性剂十六烷基三甲基溴化胺(CTAB)、十二烷基硫酸钠(SDS)和聚乙二醇(PEG)及其含量对产物形貌和相组成的影响。结果表明, 采用这三种表面活性剂制备的产物都是羟基磷灰石, 部分样品含有少量碳酸钙杂质。加入CTAB和SDS均会对纤维的生长起到抑制作用, 得到纤维与球形团聚体并存的产物, 而PEG的加入在一定程度上促进了纤维的生长。

Abstract:

Hydroxyapatite fiber with high crystallinity was successfully fabricated by hydrothermal homogeneous precipitation synthesis with Ca(NO3)2·4H2O and (NH4)2HPO4 as precursors. Effects of the surfactants include cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS) and polyethylene glycol (PEG), and different amounts of them on the morphology and phase composition of the obtained products were investigated. Results show that the products obtained by using the three surfactants are all hydroxyapatite with minor CaCO3 in some samples. The addition of both CTAB and SDS inhibits the growth of the fibers, leading to the coexistence of fibers and spherical aggregates. However, the addition of PEG can promote the growth of fibers to some extent.

Key words: hydroxyapatite fibers, surfactants, hydrothermal homogeneous precipitation, morphology
